Application filed June 26, 1905. Renewed July To all wltmn, 71!; [rur l none/311M I Be it known that 1, JEAN NEUKIRC/HEN, a subject of the Emperor of Germ any residing at Cologne, Germany, have invented certain new and useful Improvements in egetahlej Cutters, of which the following is a specification.

My invention relates to improvements in is fully described and explained in this specification and shown in the accomp anyingdrawings, in which Figure 1 is a side elevation with the cover partly removed along the line 1' 1. of Fig. 3. Fig. 2 is a side view of the conical grater and a fragment of the main casing. Fig. 3 is a vertical cross-section on the line 3 3 of Fig. 1. Fig. l is an end elevation of the worm. Fig. 5 is. a side View of a modified form of grater; and Fig. 6 is across-section of the same, taken in the line 6 6 of Fig. 5.

Referring to the drawings, A is a frame having a hopper a at its upper. end and a clamp a/ at its lower end, by which means it can be attached to a table or other support. The center of the frame consists of a horizontal cylindrical portion A, one side of which is closed by a wall a provided with a journal (1 to receive a shaft B. rotatable by means of a crank B. The opposite face of the hori zontal cylindrical portion. A is open and is provided near its edgewith a plurality of radially-projecting'lugs e C indicates a hollow metallic cone, the larger end of which fits over the open end" of the cylindrical portion A of the frame and is held thereon by engagement with the lugs cu with hayonet'slots c at the end of a cone. The opposite or smaller end of the cone is closed. by means of a block c which acts as a bearing for the opposite end of the shaft B. The cone G is provided with a plurality of small perforations c, the being depressed on one side of each of said perforations at c to form cutting edges.

1) indicates a spiral weh preferably integral with the shaft, the width of said web decreas ing graduallytoward the small end of the cone, so that the spiral formed by the Wehlits closely therein. it will be seen that the web is not arranged in a true spiral, but is provided at intervals with a plurality of comparatively steep steps which average pitch of the web. i

The material to be operated upon hopper and from there passes into the cylindrical portion of the frame. As the crank. is turned the spiral web on the shaft operates to convey the material into the cone or grater D. As the shaft rotates a portion of the in aterial eventually lodges just in advance of one of the steps in the web, and

when it reaches this position there is only a slight tendency to move forward, theforce of the machine opera-tin to move the m aterial around the grater. a l l hen the material is sufliciently reduced '11 size as to require but little force to advance it into the cone, it the next step isreaehed, when it is again moved around and around in the grater for a considerable period.

I am aware that heretofore devices have moves on until been made for breaking up material in which a screw eonveyer forces the material through perforations; but my these in that practically the grating or cuttmg one, very device differs fromentn'e action is a little, if any, of

My device is not a squeezing machine, but is rather a true grater or cutter having an automatic material feed. It

grater can be ures but 5 and 6 are adapted to produce portions of material r tively small cross-se ether long and of mmparaction, suclnfor instance,

as th vegetables ordinarily used in making l reneh fried potatoes.
